the system board when you turn the system on. Be careful not to bend the pins on
the LGA socket.
Identify the pin-1 corner of the card by locating the tiny gold triangle
a
on one corner of the card. Place this corner in the same corner of the
ZIF socket identified by a corresponding triangle on the system board.
Ensure that the socket-release lever is fully open.
b
With the pin-1 corners of the card and socket aligned, set the
c
processor lightly in the socket.
Because the system uses a ZIF processor socket, do not use force.
When the card is positioned correctly, it drops down into the socket
with minimal pressure.
Close the processor shield.
d
Rotate the socket release lever down until it snaps into place, securing
e
the card.
